SPECIFICATION forming part of Letters Patent No."746,309, dated December8, 1903.

' Application filed February 14,1901. Serial No. 47,30.6.' armada.)

.To all whom it may concern: Be it known that I, LOUIS P. EISENBEIS, acitizen of the United States of America, residing in Ottumwa, in thecounty of Wapello and State of Iowa, have invented certain new anduseful Irfiprovement'sin Paper-Bag Machines, of which the following is atrue and exactdescription, referencebeiug had to the accompanyingdrawings, which form a part IO thereof.

Myinvention relates to machinery formal;- ing paper bags,andparticularly to that part of the mechanisinwhich has for its functionthe folding ofa continuous web of paper into a tube adapted to becut upinto bag-blanks and converted into paper bags. In machinery of this kindthe Web of'paper is generally folded over a device called a former, thefolding being accomplished by a series of folding devices actingsuccessively upon the paper and in connection with the former, so as togradually fold the paper around the former and'to thedesigned sectionalshape. These folding devices have heretofore been made individuallyadjustable, and sometimes adjustable in groups; but the object of myinvention is, Without necessarily interfering with the iniudividualadjnstability of the folding devices, to provide means by which thefolding devices as a whole can be rapidly and at will retracted from orbrought to operative position with regard to the former Without inter'fering with their individual adjustment andin such manner as to givefree access .to the paper from below; and the leading feature of myinvention consists inseouring the folding devices on each side of theformer to retractable supports or tables coupled to move in and outsimultaneously, with which they can 40 be moved toward oraway from theformer at will, the machine having no table below said retractablesupports.

Other features of myinvention will be best understood as described inconnection with the drawings in which my invention is illustrated, andin which- 7 a Figure 1 is a. plan view of a portion of a paper-bagmachine embodyinginyinvention. Fig. 2 is a side elevation of the sameportion of the machine. Fig. 3 is also a side elevation, but taken onthe section-line 3 3 of Fig. I

1. Fig. 4 is a cross-sectional view taken as on scction-line 4 4 of Fig.'3: Fig. 5 is a crosssectional view taken as on the section-line 5 5 ofFig. 1." Fig. 6 is a cross-sectional view'55 taken as on thesection-line 66 of Fig. 3. Fig. 7 is a perspective view with the end ofthe movable. tables: and former shown as taken on thesection-line 7 7 ofFig. 1. Fig. 8 is a cross-sectional view taken as on the sectiOn-lineS 8of Fig." 2, and Fig. 9 is a cross-sectional view taken as on thesectionl line99of Fig.2.

A A indicate the supporting-framework of the machine. v

B indicates the' -roll of paper from which the Web is drawn'forconversion into a tube, the web passing from the'roll B over the rollerB, thence under the r0ller'B thence over the rollerB thence under theroller B from which it passes beneath the former, (in- 'dicated at D.) Y0 indicates a'paste-trough, and O a paste? *wheelrunning in said troughand acting'to apply a line of paste to one edge of the paper as itpasses over the roll'B The former D is preferably of theH shaped formindicated in thedrawings', with its up- 1 per and lower faces graduallyconverging.

D D indicate upwardly-extending fingers 8'0 situated one on each side ofthe formerD near its larger end, said fingers extending upward from'theadjustable plates D and be- 'ing secured in place by bolts passingthrough slots in said'plates and acting to clamp them against the tablesE E. The action of these fingers is to turn the web of paper upward, asindicated in Fig. 4.

D D are folding-wheels journaled loosely on studs rising from plates Dwhich plates, like the plates D are secured to the tables v E by boltspassing through slots in the plates. The action-of these wheels is topress the pal per in between the arms of the H-shaped former, asindicated in Fig- 5 D is a finger or plate acting to press one edge ofthe web downupon the top of the former in advance of the other edge. Asshown, it is secured to a finger D by means of a nut and bolt, and maybe adjustable, as I00 shown in Fig. 7.

D D are fingers acting to press both edges of the web down upon the topof the former l and the one edge over the other, as shown in Fig. '7,and d d are fingers acting to press the tucked-in portions of the webwell in be tween the upper and lower plates of the former, as shown inthe same figure. Both of these fingers are, as shown, secured to platesD",wnieh in turn are adj ustably secured on tables E by bolts passingthrough slotsiu the plates.

D D are presser-wheels converging toward each other in the direction ofthe movement of the web over the former and arranged to act upon the topof the web, the said wheels being secured in bearings which aresupported on standards D D", in turn secured to the tables E.

D is a roller situated in front of the presserwheels D and acting on thetop of the folded web which passes between the roller and the top of theformer, as indicated in Figs. 3 and 9, and in Fig. 3 it will be observedthat the lower plate of the former (indicated at D extends beyond theupper plate, as is usual in machines of this character.

E indicates a narrow stationary table-section extending parallel to andbeneath the center of the former D, and E E indicate supporting-tablesfor the paper-folding devices described, said tables resting upon theframework of the machine and being laterally movable thereon, so thatthey can be moved away from or toward the stationary table E at will,and obviously as they are moved away from the said stationary table andaway from the former D they will simul taneously retract from operativeposition all the folding devices which coact with the former in makingthe tube. It is important that the folding devices should be rapidly andsimultaneously retracted and brought to operative position, and this 1provide for in the construction shown by forming on the tables E thedownwardlyextending lugs E E &c., (see Figs. 2, 3, and 8,) connectingthese lugs through links E with the oppositely-extending arms of a leverE secured to a rock-shaft E, which in turn is actuated through alever-arm E by a link E secured to a hand-lever E It will be obvious(see Fig. 8) that by raising the hand-lever both of the tables E areinstantly moved out away from the former, while by depressing thehand-lever they are instantly brought back to accurate operativeposition.

E (see Fig. 3) indicates an opening through the stationary table E,through which extends the upper part of a printing-roller b, and e 6(see Fig. 6) indicate openings in the inner edge of the tables E E,through which the cutter-blades F F operate.

An essential feature of my invention consists in the constructionwhereby no table or similar obstruction exists beneath the tablesections E E E, by reason of which the retraction of the sections E Eleaves the former and the paper accessible from below as well as fromabove.

The rinting-rollerh o crates in connec-.

tion with a presser-roller b, between which and the printing-roller theweb of paper passes between the guiding-rollers B and B Ink is appliedto and distributed on the inkingroller b by the inking-rolls 12 which inturn receive ink intermittently from the oscillating roller 17 which inone position receives ink from an inking-roller b working in anink-trough b and in the other position imparts a layer of ink to thenearest of the stationary inking-rollers W, as shown in Fig. 3. Theprinting-roller b is driven through a bevel-wheel F actuated by abevel-wheel F on the shaft F; but as this printing mechanism forms nopart of my present invention it need not be further described orillustrated with more detail.

F F, as already stated, are slitting-knives, the function of which is tocut longitudinal slits in the under layer of the paper passing over theformer D. These knives are secured to and rotated with a shaft F, theknives passing through the opening e in the upward part of theirrevolution and of course not interfering with the in-and-out movement ofthe tables E. The shaft F is driven by a bevel-gear F engaged andactuated by a bevel-gear F on the shaft F said shaft in turn beingdriven through a bevel-gear F at its end by a bevel-gear F secured onthe transverse shaft F ,which shaft in turn is driven by a gear-wheel Fand connections not further shown in the drawings. As shown in thedrawings, the shaft F has arranged opposite to its end (see Fig. 1) astationary bevel-gear E, which engages and drives bevel-gears F and F toeach of which is secured a shaft F carrying at its end a striker F Thebearings for the shafts F are indicated at F and are secured to theshaft F through a plate F so that the said bearings with the bevel-gearsand shafts rotate with the shaft and in rotating are revolved by theirengagement with the stationary bevel gear-wheel F The result of thismovement is that each of the strikers F is caused to move across infront of the end of the former and in connection with knives (not shownin the drawings) sever the tube into blanks. This arrangement of thestrikers does not form a part of my present invention and need not,therefore, be further described or illustrated.

The operation of my machine as above described is well understood andhas been sufficiently described.

The advantage of my construction,by which the paper-folding devices canbe rapidly retracted from and brought to operative position, will be atonce appreciated, as it enables a new web to be inserted in the tubeforming part of the machine or a torn web extracted and straightened outwith the least possible delay and disarrangement of the folding deof theordinary staiionary'table to perform its most useful function-namely,the holding, 0f the paper against the bottom of the former. Having nowdescribed my inventiomwhat I claim as new, and desire to secure byLetters Patent, is-- 1. In a tube-forming mechanism, the combinationwith a former, over which the paper is formed into a tube, oftable-sections lyingon each side of the former andlaterally mov-v ablewith respect to it, a series of web-folding devices secured to thetable-sections, and

means for throwing the table-sections in and out of operative relationwith the former, the underside of the former being freely accessiblefrom below when the sections are out of operative position.

2. In a tube-forming mechanism, the combination with a former over whichthe paper is formed into a tube, and a narrow stationary table-section,lying lengthwise below said former, of table-sections, lying on eachsideof the stationary section and the former and laterally movable withrespect to it, a series of web-folding devices adj ustably secured tothe movable table-sections, and means for throwing the table-sections inand out of operative relation'with the former.
